Dogs have been human companions for thousands of years, earning the title of “man’s best friend.” Known for their loyalty, intelligence and affectionate nature, dogs are the most popular pet in the United States, with over 90 million dogs living in households across the country.
Historically, dogs were domesticated from wolves around 15,000 years ago. Early humans relied on them for hunting, guarding and herding livestock. Over time, selective breeding has resulted in hundreds of distinct dog breeds, each with unique traits and characteristics.
Today, dogs are primarily kept as pets, providing companionship, comfort and even assistance. Many dogs serve as therapy animals, guide dogs for the visually impaired or working dogs in roles like search-and-rescue, police work and military service. Their strong sense of smell and trainability make them valuable partners in these important tasks.
Whether as playful family pets or hardworking service animals, dogs continue to enrich human lives with their unconditional love and diverse skills.
